Fluoxetine and premature ejaculation: a double-blind, crossover, placebo-controlled study.
The purpose of this study was to investigate the effect of fluoxetine on sexual function in men with premature ejaculation and/or erectile dysfunction and control subjects in a prospective, double-blind, placebo-controlled, crossover study. There were four groups: (1) premature ejaculation (PE, N = 9); (2) premature ejaculation and erectile dysfunction (PE/ED, N = 9); (3) erectile dysfunction (ED, N = 7); and (4) healthy, sexually functional control subjects (N = 15). The study consisted of three 4-week periods: fluoxetine, washout, and placebo (or vice versa). Fluoxetine began at 5 mg/day for 2 weeks, followed by 10 mg/day for 2 weeks. At weeks 0, 4, 8, and 12, subjects visited the laboratory for evaluation of sexual function and assessment of erectile response, ejaculation, and sexual arousal to visual erotic stimulation without and with concomitant vibrotactile stimulation to the penis. At home, daily logs for sexual activities and feelings of well-being were maintained, and nocturnal penile tumescence was measured. The latency to ejaculation increased significantly in the PE/ED group (p = 0.03) and in the PE and the PE/ED group taken together (p = 0.007) but not in the PE group alone. Fluoxetine stimulated objectively but not subjectively measured erectile response during laboratory assessment in all groups. No major side effects were reported. In conclusion, fluoxetine (5-10 mg/day) was effective in increasing latency to ejaculation in patients with PE (PE and PE/ED groups combined).
